I have Oem gm 4 gauge clusters in stock and ready to ship these are new and never have been installed in a car, some of these might have very light service sctraches on them. If you have a 2013 car you need a gen5diy harness but if you have a 2010-2012 car you need the oem gm harness. With the harness my kit will sell for $235.00shipped and includes everything needed to install. If you have any questions let me know

V8 Manual:2
AUTO:3
ZL1 Manual:1

if you would like to buy just the gauge pack they will be $190.00shipped.
